7 Common Signs You Need A Root Canal

A painful and unexpected toothache can stop you cold. But can it be anything more dangerous, like an infected tooth, or is it simply a small cavity? When a tooth is severely decaying or diseased, root canal therapy is a very successful option to treat that. Ignoring the warning signals can turn into tooth loss, abscesses, and excruciating pain.

So, how can you tell when a dental appointment is necessary? These are 7 signs that say a root canal therapy is now necessary.

1. Chronic Pain In Tooth

One of the most typical indicators of an infection is a persistent toothache. Keep an eye out if you suffer from: 

• A severe, pulsating pain inside the tooth.
• Pain that persists even after taking medication. 
• Uneasiness that radiates to your jaw or ears.

A severe and persistent ache is a warning sign that there may be damage to the nerve in your tooth.

2. Sensitivity To Temperature

Do your teeth hurt sharply when you eat ice cream or drink hot coffee? A tooth that is more sensitive to temperature changes may have exposed nerves as a result of decay or infection. You should visit a dentist right away if the sensitivity continues for more than a few seconds. 

3. Swollen or Tender Gums

Swollen, red gums around a tooth may signal an infection. Look for tenderness, a pimple-like bump, or oozing pus—these signs may indicate the need for a root canal therapy.

4. Darkening or Discoloration of the Tooth

A tooth that turns gray or dark yellow may indicate that the inner nerve is dying due to infection or trauma. Unlike surface stains from coffee or smoking, this discoloration comes from the inside of the tooth and won’t go away with whitening treatments.

5. Pain When Chewing or Touching the Tooth

If you feel a sharp pain when biting down, your tooth may have a severe cavity or an infected pulp (the inner soft tissue of the tooth). This could indicate that the infection has reached the root, requiring a root canal to prevent further damage.

6. A Cracked or Chipped Tooth

A cracked or chipped tooth exposes the nerve to bacteria, increasing infection risk. If you notice a crack, sensitivity, or past trauma, see a dentist ASAP.

According to the American Association of Endodontists, over 15 million root canals are performed every year in the U.S., helping patients save their natural teeth and avoid extractions.

7. A Pimple on Your Gums (Dental Abscess)

A pimple-like bump on your gums may signal a dental abscess, leading to pus, swelling, and bad breath. If it’s left untreated, it can spread. A root canal can help save your tooth.

Root canals are a safe, effective way to relieve pain and save your tooth. If you notice any of these signs, visit our dentist early to prevent complications. Your smile deserves the best care.
